Abstract
A system and method for increasing the refrigeration capacity of a direct expansion refrigeration system having an inlet separator and a liquid ejector in which heat absorbing capacity is increased by increasing coil liquid refrigerant flow but retaining liquid free evaporator outlet flow and also retaining few degrees of superheat. The liquid refrigerant flow is increased through local recirculation of liquid from coil outlet to coil inlet through an ejector which pumps the unevaporated liquid refrigerant from a lower pressure (suction pressure) to a higher pressure. The ejector is powered by either saturated or subcooled liquid after the expansion valve.
